2. What is Important?
Making Sure that the patient eats
Making Sure that the patient eats the Right Foods
3. Objectives of this Talk What is Malnutrition?
Why is this Important in the hospitalized patient?
Specific Diets
Other added information
4. Malnutrition WHO (World Health Organization) definition:
Cellular imbalance between the supply of nutrients and energy AND the body’s demand for them to ensure growth, maintenance and specific functions
5. Why Is This Important in the Hospitalized Patient? Disease-related malnutrition is a major health care problem and results in a reduced ability to prevent, fight, and recover from disease.
Malnutrition is associated with postoperative complications, increased length of hospital stay, and even death.
6. To Whom Should We Pay Attention? 40 percent of older people are malnourished when they are admitted to hospital
Nutritional status of 60 percent of all older patients will deteriorate further while they are in hospital
Decreased Food Intake Represents an Independent Risk Factor for Hospital Mortality
7. One Study in Australia 58 percent of the patients, who were aged 65 or over, had problems eating.
Just under a third (31 percent) left more than two-thirds of their meal
Only 15 percent had eaten their whole meal.
More than half of the patients they studied (55 percent) had problems opening food.
About a third found it difficult to use cutlery (36 percent). Blackwell Publishing Ltd. (2006, September 25). Malnutriton A Major Issue Among Hospital Patients Over 65. ScienceDaily.

8. More Results More than a fifth (23 percent) were too far away from their food.
Interruptions were also frequent.
One in five patients (19 percent) had a doctor's visit during mealtimes
more than half (51 percent) had mealtimes interrupted by other staff, mostly nurses (92 percent).
9. What Happens in the Starving, Stressed Patient? Stress/Trauma activates the sympathetic nervous system (flight or flight)
Utilization of carbohydrates are inhibited and hyperglycemia often occurs
Insulin secretion declines
Blood levels of glycogen, growth factor, catecholamines, thyroid hormones, ACTH, ADH all increase
Lipolysis is activated, gluconeogenesis and proteolysis is acclerated, large amounts of protein are consumed to provide the energy needed
10. How To Evaluate ThisNutritional Assessment
Clinical History
Exam and Body Composition Analysis
Indirect Calorimetry
Anthropomorphic Measurements
Functional Studies of Muscle Function
Biochemical Measurements
11. What is Easy and Effective? History
At admission or during stay: 10% weight loss or more suggests protein malnutrition
NPO or Clears > 5-7 days
Use one of the simple questionnaires:
The Short Nutritional Assessment Questionnaire (SNAQ)
The Subjective Global Assessment
DETERMINE
12. The Short Nutritional Assessment Questionnaire (SNAQ) Question Score
Did you lose weight unintentionally?
>6 kg in the past 6 mo 3
>3 kg in the past month 2
Did you experience a decreased appetite over the past month? 1
Did you use supplemental drinks or tube feeding over
the past month? 1
Scoring:
Well nourished: 0 or 1 points
Moderately Malnourished: 2 points
Severely Malnourished =3 points
13. Results of One Study for SNAQ Recognition of malnutrition improved from 50% to 80% with the use of the SNAQ malnutrition screening tool during admission to the hospital.
The standardized nutritional care protocol added ˜600 kcal and 12 g protein to the daily intake of malnourished patients.
Early screening and treatment of malnourished patients reduced the length of hospital stay in malnourished patients with low handgrip strength (ie, frail patients).
To shorten the mean length of hospital stay by 1 d for all malnourished patients, a mean investment of €76 (US$91) in nutritional screening and treatment was needed. Effectiveness and cost-effectiveness of early screening and treatment of malnourished patients. Am J Clin Nutr

14. Subjective Global Assessment Strengths:
Combines self report, clinical assessment and simple bedside evaluation for dysphagia.
Identifies patients who may benefit from nutritional counseling or home delivered meals
Includes evaluation of activities of daily living, depression, poor oral health, polypharmacy or status of underlying chronic conditions.
Limitations:
A significant proportion of the instrument requires patient or proxy report and depends on the history being available and correct.
15. DETERMINE Strengths:
Quick and easy to administer 10 item questionnaire to patient or proxy.
The checklist identifies patients who may benefit from nutritional counseling or home delivered meals
Evaluates activities of daily living, depression, poor oral health, polypharmacy or status of underlying chronic conditions
Limitations:
The instrument is dependent on the patient or proxy having the information and being forthright.
16. What to Look For?Objective Findings/Exam
Weight/Ideal body weight (<85% predicted)
(IBW See Metropolitan Life Insurance Company Charts)
BMI <18 kg/m2
Anthropometrics = weight to height assessment – difficult since there are fluid shifts or accumulations and inaccurate wts
Physical Exam – temporal wasting, thenar atrophy, …
GI tract functioning – i.e. previous surgery
17. What to Test? Immune Function – lymphocyte <1800, skin testing, anergy
Prealbumin
T1/2 = 2 days
Falsely elevated with RF, Hodgkin’s Disease, Steroids
Falsely low with acute catabolic stress, hepatic disease, stress, infection, surgery
Albumin
T1/2 = 21 days so does not reflect acute changes
Falsely elevated with dehydration
Falsely low with edema, hepatic disease, anemia, malabsorption, diarrhea, burns, volume overload, ESRD
Transferrin
T1/2 = 7 days
Fat Soluble Vitamins:
A, E, and 25-hydroxyvitamin D can be measured directly.
Prothrombin time is used as a proxy to measure vitamin K.
18. More Tests U24 hr for Urea nitrogen (cannot be used with RF)
Nitrogen balance used to measure degree of catabolism
Nitrogen Balance= Intake – Output
= Protein Intake/6.25 – (Urine urea nitrogen +4) [the 4 is to account for the skin+stool loses]
Goal is to have at least 3 to 4 grams positive for growth and repair
Serum carotene
correlated with vitamin A status
can be used as a surrogate marker of malabsorption and nutritional status
Retinol Binding Protein (RBP) - used to determine visceral protein mass in nutritional studies related to health.
measurement of serum retinol levels (levels less than 20 micrograms/dL suggest deficiency) or
the ratio of retinol:RBP (a molar ratio <0.8 suggests deficiency)
19. Requirements in General Figure out Calories needed then what percentages based on nutrients
Nutrients
3 major sources for the Fuel/Calories
Amino Acids/Protein = 15%
Non Stressed Protein = 0.8 to 1 gm/kg/day or 150 mg of nitrogen/kg/day
Stressed = 1.7g/kg/day or 200 -250 mg N/kg/day
Fat = 25-50%
CHO = 35-65%
Plasma Electrolytes
Vitamins and Micronutrients
Fat Soluble Vitamins are more likely than Water Soluble to be low if malnourished

23. Harris Benedict FormulaTo Determine Total Daily Calorie Needs = BMR x Activity
If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375
If you are moderatetely active (moderate exercise/sports 3-5 days/week) : Calorie-Calculation = BMR x 1.55
If you are very active (hard exercise/sports 6-7 days a week) : Calorie-Calculation = BMR x 1.725
If you are extra active (very hard exercise/sports & physical job or 2x training) : Calorie-Calculation = BMR x 1.9

33. Calcium Calcium Citrate
recommended form of calcium supplements because it is best absorbed by the body.
Calcium Citrate does not require the presence of stomach acid to dissolve.
Limit your supplement to no more than 500 mg at one time to increase absorption.
All calcium supplements should include Vitamin D,
Goal is 1500 mg of calcium from food and supplements.
Do not take calcium supplements around the same time as prenatal or iron supplements.
The % daily value of Calcium on food labels
There is an easy way to figure out how many milligrams (mg) of calcium is in food items. All you have to do is remove the % from the Daily Value for calcium and add a "0"!
34. Vitamin D 1- 70 years old = 600 IU/day
> 70 years old = 800 IU/day
Upper safe limit is 4000 IU/day
Sources
Sunlight – 15-30 minutes/day
Foods: codliver oil, salmon canned, tuna fish canned, shrimp cooked, fortified milk/yogurt/orange juice
Medicines that interfere with Vit D

37. Iron Iron tablets may be taken 3 times a day, in between meals.
Avoid taking iron with a phosphate binder (Calcium carbonate, Tums, Phos- Ex, Phos-Lo, Cal-Carb, Calcium acetate)
Large amounts of Calcium bind with iron and make iron less available for absorption by the body.
If a calcium binder is taken with meals, wait at least one hour after a meal before taking iron.
Avoid taking iron with coffee or tea (wait at least one hour), as well as with
Foods high in vitamin C will increase absorption of iron in your body.
